Deciding between sidewall ratings

Hey guys, I just bought an 07 double cab for a daily and hunting truck. It needs tires soon so I’m looking at Nitto Terra Grappler G2 in 265-70/r17. I’ve run nittos on my old truck that I’m selling and had good luck. So going from a full size truck to a taco I’m unsure how stiff a sidewall I need. I’m not doing anything hardcore, I’m trying to leave the truck pretty stock, thinking just tires and shocks. But the trails I have to go down are kinda rocky. So the nittos come in 265/70R17 115T And LT265/70R17 E 121/118S. The 115T, 121/118S is where I get confused. Could you guys make suggestions and explain why? Thanks


Edit: tires on it now, assuming stock, are p265-65/r17

 

Hello Kyle, welcome to TW. Check out, tirerack.com. They have a section that explains weight ratings and speed ratings. The section is called "Tire Tech", check it out.

Never mind what I said, I missed it completely. Good luck finding your tires.

 

Personally, unless you're building an expo rig and adding a ton of weight to it, hauling/towing frequently, or doing hardcore rock crawling, I think you'll be happier with the P-rated tires. They should be adequate for your needs, without pointlessly slashing your gas mileage and creating more wear and tear on your front end components (and your back).

 

I run a beach rig some fire trails, truck camping. P rated 116 load tires is what I’m running. Could not find and C load 265/70 17’s in a tire I wanted to run.
